摘　　要：以一个典型的桅杆-天线系统为例,探讨了封闭式隐身桅杆的设计方法,形成了桅杆-天线系统隐身初步设计原则。为了保障电磁收发设备的正常工作,研究了封闭式桅杆上透波窗的设计方法和相应的频率选择表面(FSS:Frequency Selective Surface)技术。对封闭式隐身桅杆方案与普通桅杆的电磁散射性能进行了对比分析。结果表明:封闭式隐身桅杆能在宽广的角域范围内有效降低桅杆-天线系统的雷达散射截面(RCS:Radar Cross Section),大幅度提高桅杆-天线系统的隐身性能。The design of an enclosed stealth mast of＇a typical mast-antenna system is discussed in this paper, and the preliminary design method and principle is presented. To ensure the normal function of the observation and communication equipments, the de- sign method of transmission windows and the using of frequency selective surfaces （FSSs） are investigated. A comparison between the scattering characteristic of the original mast and its enclosed stealth mast design is conducted. The results show that the en- closed stealth mast can effectively reduce the radar cross section（RCS） of a mast-anten- na system in a broad angular domain and significantly improve its electromagnetic scattering performance.
